* mmc: rtsx: Revert "mmc: rtsx: add support for pre_req and post_req"Micky Ching2014-05-081-91/+41
| | | | | | | | | | | | | | | | | | | This reverts commit c42deffd5b53c9e583d83c7964854ede2f12410d. commit <mmc: rtsx: add support for pre_req and post_req> did use mutex_unlock() in tasklet, but mutex_unlock() can't be used in tasklet(atomic context). The driver needs to use mutex to avoid concurrency, so we can't use tasklet here, the patch need to be removed. The spinlock host->lock and pcr->lock may deadlock, one way to solve the deadlock is remove host->lock in sd_isr_done_transfer(), but if using workqueue the we can avoid using the spinlock and also avoid the problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for non-blocking request, pre_req() runs dma_map_sg() and post_req() runs dma_unmap_sg(). This patch can increase card read/write speed, especially for high speed card and slow CPU(for some embedded platform). Users can get a great benefit from this patch. if CPU frequency is 800MHz, SDR104 or DDR50 card read/write speed may increase more than 15%. test results: intel i3(800MHz - 2.3GHz), SD card clock 208MHz performance mode(2.3GHz): Before: dd if=/dev/mmcblk0p1 of=/dev/null bs=64k count=1024 67108864 bytes (67 MB) copied, 1.18191 s, 56.8 MB/s After: dd if=/dev/mmcblk0p1 of=/dev/null bs=64k count=1024 67108864 bytes (67 MB) copied, 1.09276 s, 61.4 MB/s powersave mode(800MHz): Before: dd if=/dev/mmcblk0p1 of=/dev/null bs=64k count=1024 67108864 bytes (67 MB) copied, 1.29569 s, 51.8 MB/s After: dd if=/dev/mmcblk0p1 of=/dev/null bs=64k count=1024 67108864 bytes (67 MB) copied, 1.11218 s, 60.3 MB/s Signed-off-by: Micky Ching <micky_ching@realsil.com.cn> Signed-off-by: Chris Ball <chris@printf.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On PXT and COMe-cPC2 boards it is observed that the hardware mutex is acquired but not being released during initialization. This can result in a hang-up during boot if the driver is built into the kernel. Releasing the mutex twice if it was acquired fixes the problem. Subsequent request/release cycles work as expected, so the fix is only needed during initialization.

'tps65910->irq_data' will be pointing to already freed memory (because regmap_add_irq_chip() will free it on error) This results in invalid memory access during driver remove because the tps65910_irq_exit() tests whether 'tps65910->chip_irq' is not zero.

Differences from previous iTCO versions include: - The ACPI space is enabled in the "ACPI base address" register instead of the "ACPI control register" - The "no reboot" functionality is set in the "Power Management Configuration" register instead of the "General Control and Status" (GCS) register or PCI configuration space. - The "ACPI Control Register" is not present on v3. The "Power Management Configuration Base Address" register resides at the same address is Avoton/Bay Trail. To differentiate these newer chipsets create a new v3 iTCO version and update the MFD driver to support them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pm8xxx-irq.c code is practically mandatory given that the pm8921-core driver will WARN about it missing and the Kconfig marks it as default y when a PM8xxx chips is enabled. The only reason the file was split out was because we planned to support other pm8xxx chips with different pm8xxx-core.c files. Now that we have DT on ARM this isn't necessary because we should be able to support all the ssbi based PM8xxx chips in one driver and one file with no data bloat. Let's move this code into the only driver that uses it right now (pm8921) so that it's always compiled when needed. In the future we can rename pm8921-core.c to something more generic.

There is also some small amount of correction done in this patch: it splits the revision code and correctly names it according to the hardware specification and moves the dev_info() call before the variant ID test.
