* docs: arm: convert docs to ReST and rename to *.rstMauro Carvalho Chehab2019-07-151-3/+3
| | | | | | | | | | | | | | | | | | Converts ARM the text files to ReST, preparing them to be an architecture book. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

* ARM: samsung: Limit SAMSUNG_PM_DEBUG config option to non-Exynos platformsBartlomiej Zolnierkiewicz2018-11-181-0/+1
| | | | | | | | | | | | | | | | "Samsung PM Suspend debug" feature (controlled by SAMSUNG_PM_DEBUG config option) is not working properly (debug messages are not displayed after resume) on Exynos platforms because GPIOs restore code is not implemented. Add PLAT_S3C24XX, ARCH_S3C64XX and ARCH_S5PV210 dependencies to SAMSUNG_PM_DEBUG config option to hide it on Exynos platforms. Then convert Exynos code to not require <plat/pm-common.h> header (use pr_debug() directly instead of S3C_PMDBG() macro and remove redundant s3c_pm_*() calls).

* ARM: samsung: Limit SAMSUNG_PM_CHECK config option to non-Exynos platformsBartlomiej Zolnierkiewicz2018-10-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "S3C2410 PM Suspend Memory CRC" feature (controlled by SAMSUNG_PM_CHECK config option) is incompatible with highmem (uses phys_to_virt() instead of proper mapping) which is used by the majority of Exynos boards. The issue manifests itself in OOPS on affected boards, i.e. on Odroid-U3 I got the following one: Unable to handle kernel paging request at virtual address f0000000 pgd = 1c0f9bb4 [f0000000] *pgd=00000000 Internal error: Oops: 5 [#1] PREEMPT SMP ARM [<c0458034>] (crc32_le) from [<c0121f8c>] (s3c_pm_makecheck+0x34/0x54) [<c0121f8c>] (s3c_pm_makecheck) from [<c0121efc>] (s3c_pm_run_res+0x74/0x8c) [<c0121efc>] (s3c_pm_run_res) from [<c0121ecc>] (s3c_pm_run_res+0x44/0x8c) [<c0121ecc>] (s3c_pm_run_res) from [<c01210b8>] (exynos_suspend_enter+0x64/0x148) [<c01210b8>] (exynos_suspend_enter) from [<c018893c>] (suspend_devices_and_enter+0x9ec/0xe74) [<c018893c>] (suspend_devices_and_enter) from [<c0189534>] (pm_suspend+0x770/0xc04) [<c0189534>] (pm_suspend) from [<c0186ce8>] (state_store+0x6c/0xcc) [<c0186ce8>] (state_store) from [<c09db434>] (kobj_attr_store+0x14/0x20) [<c09db434>] (kobj_attr_store) from [<c02fa63c>] (sysfs_kf_write+0x4c/0x50) [<c02fa63c>] (sysfs_kf_write) from [<c02f97a4>] (kernfs_fop_write+0xfc/0x1e4) [<c02f97a4>] (kernfs_fop_write) from [<c027b198>] (__vfs_write+0x2c/0x140) [<c027b198>] (__vfs_write) from [<c027b418>] (vfs_write+0xa4/0x160) [<c027b418>] (vfs_write) from [<c027b5d8>] (ksys_write+0x40/0x8c) [<c027b5d8>] (ksys_write) from [<c0101000>] (ret_fast_syscall+0x0/0x28) Add PLAT_S3C24XX, ARCH_S3C64XX and ARCH_S5PV210 dependencies to SAMSUNG_PM_CHECK config option to hide it on Exynos platforms.

The advantage is that a driver that happens to call dma_set_mask() on one device doesn't implicitly change the mask for the other devices as well. This is more of a theoretical problem, as obviously nothing does it for the devices in this file (or they would have always been broken), but it feels cleaner that way. The definition works by creating an array in place so we can take the address of it and let the compiler generate a hidden symbol for it at compile time.

Linus Walleij also has some patchs to clean up the older ARM Realview platforms by finally introducing DT support, and Rob Herring has some for ARM Versatile which is now DT-only.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the code for the s3c64xx platform is only used when booting with ATAGS based board files, but not when using device-tree. This tries to identify all the s3c64xx specific code that is unneeded when CONFIG_ATAGS is not set, so we can build a smaller DT-only kernel if configured that way. All board support is still left intact but now depends on the CONFIG_ATAGS symbol that users may intentionally disable. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The gpio-samsung driver is special in the sense that it interacts directly in multiple ways with the legacy platform code for the s3c24xx and s3c64xx platforms. In contrast, all devicetree based machines for Samsung, including the ones on those two SoC families use a different driver. The header files that define the interface between the platform code and the gpio driver are not visible when building a kernel for ARCH_MULTIPLATFORM, which prevents us from turning on this option for s3c64xx. To work around this, we now move the driver back into platform code, from where it was originally moved to as part of commit 1b39d5f2cc5c28 ("gpio/samsung: gpio-samsung.c to support Samsung GPIOs"). The long-term plan for this driver would be to remove it entirely, after all Samsung machines have been converted over to boot from DT, but there is currently no timeline for when that might happen.

I'm keeping this change separate, as there it's less obvious that this is a net win. Upsides of this are: - The ASoC drivers are completely independent from the DMA engine implementation, which simplifies the Kconfig logic and in theory allows the same sound drivers to be built in a kernel that supports different kinds of dmaengine drivers. - Consistency with other subsystems and drivers On the other hand, we have a few downsides: - The s3c24xx-dma driver now needs to be built-in for the ac97 platform device to be instantiated on s3c2440. - samsung_dmaengine_pcm_config cannot be marked 'const' any more because the filter function pointer needs to be set at runtime. This is safe as long we don't have multiple different DMA engines in thet same system at runtime, but is nonetheless ugly.
