* ARM: OMAP: DRA7: Make use of omap_revision information for soc_is* callsKeerthy2016-02-191-3/+20
| | | | | | | | | | Currently of_machine_is_compatible is used to detect the soc which employs string comparison operations. We already have all the required information in the omap_revision. Hence make use of the same like the previous OMAPs and avoid costly string comparisons. Signed-off-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: OMAP2+: Rename cpu_is macros to soc_isTony Lindgren2015-10-161-89/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | The naming for the cpu_is macros is confusing as the CPU is separate and within the SoC. Let's rename all the macros to soc_is, and let's define cpu_is also for the ones still in use. Then we can just remove the cpu_is macros once the users are fixed up. To keep the chances of breaking anything, the changes were generated with the following regular expressions: s/cpu_is/soc_is/g s/CPU/SoC/g Then the list of existing cpu_is users was generated with: $ $ grep -o -e 'cpu_is_.\+()' arch/arm/mach-omap2/*.[chS] | \ cut -d: -f2 | sort | uniq And added to the end of the soc.h. I decided to rework the earlier patches by Keerthy <j-keerthy@ti.com> to keep changes down to minimum to avoid potential errors and stick to just search and replace.

* ARM: DRA752: Add ID detect for ES2.0Vishal Mahaveer2015-09-011-0/+2
| | | | | | | | | | | | | | | | | | ES2.0 is a minor variant of ES1.1. ES2.0 is an incremental revision with various fixes including the following: - reset logic fixes - few assymetric aging logic fixes - MMC clock rate fixes - Ethernet speed fixes - edma fixes for mcasp NOTE: even though we use a compatible of dra742 and dra752, the usage in the Linux kernel is more or less interchangable - we use dra752 more often in the linux kernel compared to dra742 and 4.2-rc6 Signed-off-by: Vishal Mahaveer <vishalm@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: OMAP2+: Fix ti81xx class typeTony Lindgren2015-01-141-2/+2
| | | | | | | | | | | | | | Otherwise it will return true for cpu_is_omap34xx() which we don't want for the clocks and hwmod. It's closer to am33xx for the clocks and hwmod than to the omap34xx. We also want to be able to detect 814x and 816x separately as at least the clocks are different with 814x using a apll and 816x using a fapll for the source clocks. Note that we can also remove omap3xxx_clk_init() call as it's wrong and ti81xx are booting in device tree only mode.

* ARM: OMAP2+: AM43x: Add ID for ES1.2Lokesh Vutla2014-12-101-0/+1
| | | | | | | | | | | | | | | | | | ES1.2 is a minor variant of ES1.1. Major changes since ES1.1 are updating ROM for fixing the following boot modes: - NAND boot - UART boot - Ethernet boot - USB HOST/Client boot This patch adds ID support for AM437x ES1.2 silicon. There are no additional kernel fixes required for ES1.2 silicon.

* ARM: OMAP5: id: Remove ES1.0 supportNishanth Menon2013-10-081-2/+0
| | | | | | | | | | | | | | | | OMAP5 ES1.0 was intended as a test chip and has major register level differences w.r.t ES2.0 revision of the chip. All register defines, dts support has been solely added for ES2.0 version of the chip. Further, all ES1.0 chips and platforms are supposed to have been removed from circulation. Hence, there is no need to further retain any resemblence of ES1.0 support in id detection code. Remove the omap_revision handling and BUG() instead to prevent folks who mistakenly try an older unsupported chip and report bogus errors.

* ARM: OMAP2+: omap_device: use late_initcall_syncKevin Hilman2013-05-081-0/+1
| | | | | | | | | | | | | | | | | | | If DEBUG_LL and earlyprintk are enabled, and omap-serial.c is compiled as a module, the kernel boot hangs early as the clocks for serial port are cut while earlyprintk still uses the port. The problem is a race between the late_initcall for omap_device (which idles devices that have no drivers) and the late_initcall in kernel/printk.c which turns off the earlyconsole. Any printks that happen between this omap_device late initcall and the earlyconsole late initcall will crash when accessing the UART. The fix is to ensure the omap_device initcall happens after the earlyconsole initcall.

* | ARM: OMAP2+: Limit omap initcalls to omap only on multiplatform kernelsTony Lindgren2013-01-111-0/+29
|/ | | | | | | | | | | | | We need to make sure that multiplatform kernels don't run omap initcalls when booted on other SoCs. Do this by adding wrapper macros for the initcalls that return early if soc_is_omap() test fails. This allows us to easily change the defines later if we have SoC specific init sections available.

* ARM: OMAP: Split plat/cpu.h into local soc.h for mach-omap1 and mach-omap2Tony Lindgren2012-10-181-1/+467
| | | | | | | | | | | | | | | | We want to remove plat/cpu.h. To do this, let's first split it to private soc.h to mach-omap1 and mach-omap2. We have to keep plat/cpu.h around until the remaining drivers are fixed, so let's include the local soc.h in plat/cpu.h and for drivers still including plat/cpu.h. Once the drivers are fixed not to include plat/cpu.h, we can remove the file. This is needed for the ARM common zImage support.

* ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+Tony Lindgren2012-09-121-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the plat and mach includes need to disappear for single zImage work, we need to remove plat/hardware.h. Do this by splitting plat/hardware.h into omap1 and omap2+ specific files. The old plat/hardware.h already has omap1 only defines, so it gets moved to mach/hardware.h for omap1. For omap2+, we use the local soc.h that for now just includes the related SoC headers to keep this patch more readable. Note that the local soc.h still includes plat/cpu.h that can be dealt with in later patches. Let's also include plat/serial.h from common.h for all the board-*.c files. This allows making the include files local later on without patching these files again. Note that only minimal changes are done in this patch for the drivers/watchdog/omap_wdt.c driver to keep things compiling. Further patches are needed to eventually remove cpu_is_omap usage in the drivers. Also only minimal changes are done to sound/soc/omap/* to remove the unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's no need to include omap44xx.h. While at it, also sort some of the includes in the standard way.

* ARM: OMAP2+: Prepare for irqs.h removalTony Lindgren2012-09-121-0/+1
As the interrupts should only be defined in the platform_data, and eventually coming from device tree, there's no need to define them in header files. Let's remove the hardcoded references to irqs.h and fix up the includes so we don't rely on headers included in irqs.h. Note that we're defining OMAP_INTC_START as 0 to the interrupts. This will be needed when we enable SPARSE_IRQ. For some drivers we need to add #include <plat/cpu.h> for now until these drivers are fixed to remove cpu_is_omapxxxx() usage. While at it, sort som of the includes the standard way, and add the trailing commas where they are missing in the related data structures. Note that for drivers/staging/tidspbridge we just define things locally. Cc: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
