* ARM: OMAP: hsmmc: fix return value check in omap_hsmmc_init_one()Wei Yongjun2012-10-081-1/+1
| | | | | | | | | | | | In case of error, the function omap_device_alloc() returns ERR_PTR() not NULL pointer. The NULL test in the return value check should be replaced with IS_ERR(). dpatch engine is used to auto generated this patch.

* ARM: OMAP: Move gpio.h to include/linux/platform_dataTony Lindgren2012-09-121-0/+2
| | | | | | | | | | | | | | | | | This way we can remove includes of plat/gpio.h which won't work with the single zImage support. Note that we also remove the cpu_class_is_omap2() check in gpio-omap.c as the drivers should not call it as we need to make it local to arch/arm/mach-omap2 for single zImage support. While at it, arrange the related includes in the standard way.

* ARM: OMAP: AM35xx: convert 3517 detection/flags to AM35xxKevin Hilman2012-05-101-4/+4
| | | | | | | | | | | | | | | | | | Currently cpu_is_omap3517() actually detects any device in the AM35x family (3517 and no-SGX version 3505.) To make it more clear what is being detected, convert the names from 3517 to AM35xx. This adds a new soc_is_am35xx() which duplicates the cpu_is_omap3517(). In order to avoid cross-tree dependencies with clock-tree changes, cpu_is_omap3517() is left until the clock changes are merged, at which point cpu_is_omap3517() will be completely removed.

* ARM: OMAP: AM35xx: remove redunant cpu_is checks for AM3505Kevin Hilman2012-05-101-4/+4
| | | | | | | | | | | | | | | | | | | | | There are several checks for AM35x devices done using if (cpu_is_omap3517() || cpu_is_omap3505()) However, since the 3505 is just a 3517 without an SGX, the 3505 check is redundant because cpu_is_omap3517() will always be true whenever cpu_is_omap3505() is true. From <plat/cpu.h>: #define cpu_is_omap3505() (cpu_is_omap3517() && !omap3_has_sgx()) Therefore, remove the redunant 3505 checks. This helps move towards removal of SoC detection that depends on specific IP detection. Acked-by: Vaibhav Hiremath <hvaibhav@ti.com> Tested-by: Vaibhav Hiremath <hvaibhav@ti.com> Tested-by: Mark A.

* ARM: OMAP3xxx: HSMMC: avoid erratum workaround when transceiver is attachedGrazvydas Ignotas2012-04-041-0/+7
| | | | | | | | | | | | | If transceiver is attached to a MMC host of ES2.1 OMAP35xx, it seems 2.1.1.128 erratum doesn't apply and there is no data corruption, probably because of different signal timing. The workaround for this erratum disables multiblock reads, which causes dramatic loss of performance (over 75% slower), so avoid it when transceiver is present.

* | ARM: OMAP2+: Split omap2_hsmmc_init() to properly support I2C GPIO pinsTony Lindgren2012-02-201-27/+92
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Otherwise omap_device_build() and omap_mux related functions can't be marked as __init when twl is build as a module. If a board is using GPIO pins or regulators configured by an external chip, such as TWL PMIC on I2C bus, the board must mark those MMC controllers as deferred. Additionally both omap_hsmmc_init() and omap_hsmmc_late_init() must be called by the board. For MMC controllers using internal GPIO pins for card detect and regulators the slots don't need to be marked deferred. In this case calling omap_hsmmc_init() is sufficient. Only mark the MMC slots using gpio_cd or gpio_wd as deferred as noted by Igor Grinberg <grinberg@compulab.co.il>. Note that this patch does not change the behaviour for board-4430sdp.c board-omap4panda.c. These boards wrongly rely on the omap_hsmmc.c init function callback to configure the PMIC GPIO interrupt lines on external chip. If the PMIC interrupt lines are not configured during init, they will fail.

* ARM: OMAP: Fix kernel panic with HSMMC when twl4030_gpio is a moduleTony Lindgren2012-02-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | On some omaps twl4030_gpio has a callback to try to initialize the MMC controller. If twl4030_gpio is compiled as a module, bad things can happen because the callback function starts calling functions that are supposed to be marked __init: Kernel panic - not syncing: Attempted to kill the idle task! twl4030_gpio twl4030_gpio: can't dispatch IRQs from modules gpiochip_add: registered GPIOs 192 to 209 on device: twl4030 Unable to handle kernel paging request at virtual address b82a4c74 ... Additionally if this does not fail, warnings are produced about trying to register the MMC multiple times. Fix this by removing __init from omap_mux_get_by_name, and add checks if omap2_hsmmc_init() is getting called more than once. Note that this will get fixed properly later on by splitting omap2_hsmmc_init into two functions.

This is often because sdp3430_twl_gpio_setup lacks a __init annotation or the annotation of omap2_hsmmc_init is wrong. sdp3430_twl_gpio_setup() is called via platform data from the gpio-twl4030 module, which can be inserted and removed at runtime. This makes sdp3430_twl_gpio_setup() callable at runtime, and prevents it being marked with an __init annotation. As it calls omap2_hsmmc_init() unconditionally, the only resolution to this warning is to remove the __init markings from omap2_hsmmc_init() and its called functions. This addresses the functions in hsmmc.c. Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | hsmmc23_before_set_reg() can set MMCSDIO2ADPCLKISEL bit, which enables internal clock for MMC2. Currently this function is also called by code handling MMC3, and if .internal_clock is set in platform data (by default it currently is), it will set MMCSDIO2ADPCLKISEL for MMC2 instead of MMC3 (MMC3 doesn't have such bit so nothing actually needs to be done). This breaks 2nd SD slot on pandora. Fix this by changing hsmmc23_before_set_reg() to only handle MMC2. Note that this removes .remux() call for MMC3, but no board currently needs it and it's also not called for MMC4 and MMC5.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All of the device init and device driver interaction with omap_device is done using platform_device pointers. To make this more explicit, have omap_device return a platform_device pointer instead of an omap_device pointer. All current users of the omap_device pointer were only using it to get at the platform_device pointer or struct device pointer, so fixing all of the users was trivial. This also makes it more difficult for device init code to directly access members of struct omap_device, and allows for easier changing of omap_device internals.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch has multiple fixes together. To ensure that git bisect work across commits, all changes are clubbed together 1. Move the common control base address to control core 2. Remove the manually coeded defines and use the ones from headers. 3. Fix the the status register define in id.c for OMAP4 4. Fix all the register define in hsmmc.c 5. Use the control pad accessor API for omap4 hsmmc register accesses Signed-off-by: Benoit Cousson <b-cousson@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>

* omap4: Adding PBIAS Configuration for MMC1 Controllerkishore kadiyala2010-05-201-9/+88
| | | | | | | | | | In OMAP4, MMC1 PBIAS and its associated IO is software-controlled by CONTROL_PBIAS and CONTROL_MMC1 registers. This patch adds PBIAS configuration for MMC1 Controller during power-ON and power-OFF of regulator.

* omap_hsmmc: Allow for a shared VccQAdrian Hunter2010-02-151-0/+3
| | | | | | | | | | | | | | | | | | | | | EMMC can have two voltage supplies, Vcc and VccQ which are implemented in the code as consumer supplies vmmc and vmmc_aux. If the regulator that supplies vmmc_aux is shared with other consumers, then sending it to sleep will disrupt those consumers. However, the TWL4030-family regulators may have OFF remapped to SLEEP, in which case 'regulator_disable()' will put the regulator to sleep only when all consumers are disabled - which is the desired behaviour. This patch adds a platform data field to allow that option. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
* omap_hsmmc: Allow for power saving without going offAdrian Hunter2010-02-151-0/+3

* omap: RX51: Remux to pull eMMC lines down when powering offAdrian Hunter2010-02-151-0/+8
| | | | | | | | | | | It has been discovered that, when eMMC is powered off, current will flow from OMAP eMMC data pull-ups to the eMMC voltage supply. Configuring pads for OMAP off-mode does not help because eMMC is powered off independently of OMAP off-mode. Hence the pads are now re-configured when eMMC is powered on or off.
