| * | treewide: devm_kzalloc() -> devm_kcalloc() | Kees Cook | 2018-06-13 | 1 | -2/+4 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...". The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ expression HANDLE; type TYPE; expression THING, E; @@ ( devm_kzalloc(HANDLE, - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | devm_kzalloc(HANDLE, - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression HANDLE;

| * | soc: brcmstb: Only register SoC device on STB platforms | Thierry Reding | 2018-01-12 | 1 | -0/+5 |
| | | | | | | | | | | | | | | | | | | | | | | After moving the SoC device initialization to an early initcall in commit f780429adfbc ("soc: brcmstb: biuctrl: Move to early_initcall"), the Broadcom STB SoC device is registered on all platforms if support for the device is enabled in the kernel configuration. This causes an additional SoC device to appear on platforms that already register a native one. In case of Tegra the STB SoC device is registered as soc0 (with totally meaningless content in the sysfs attributes) and causes various scripts and programs to fail because they don't know how to parse that data. To fix this, duplicate the check from brcmstb_soc_device_early_init() that already prevents the code from doing anything nonsensical on non- STB platforms.

| | | | | | | | | | | | | | Being called during early_initcall() is early enough that it occurs before SMP initialization, which is all we care about for the Bus Interface Unit configuration. This solves lack of BIU initialization on ARM64 platforms where we do not have an anchor where to put the BIU initialization (since there are no machine descriptors).

This requires quite a lot of code in order to deal with the different HW blocks that need to be quiesced during suspend: - DDR PHY SHIM - DDR memory controller and sequencer - control processor The final steps of the suspend execute in an on-chip SRAM and there is a little bit of assembly code in order to shut down the DDR PHY PLL and then go into a wfi loop until a wake-up even occurs. Conversely the resume part involves waiting for the DDR PHY PLL to come back up and resume executions where we left. For S3, because of our memory hashing (actual hashing code not included for simplicity, and is bypassed) we need to relocate the writable variables (stack) into SRAM shortly before suspending in order to leave the DRAM untouched and create a reliable hash of its contents. This code has been contributed by Brian Norris initially and has been incrementally fixed and updated to support new chips by a lot of people.

| | | | | | | | | | | | | The brcmstb_biuctrl_init() is defined in the soc specific header file, but wasn't included in the driver file. Fix the following warning by including <linux/soc/brcmstb/brcmstb.h> in the driver: drivers/soc/brcmstb/biuctrl.c:101:13: warning: symbol 'brcmstb_biuctrl_init' was not declared. Should it be static?

| * | ARM: bcm2835: clarify RASPBERRYPI_FIRMWARE dependency | Arnd Bergmann | 2015-12-31 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | | The firmware driver can be a loadable module, but the power domain can only be built-in, so we get a build error in an allmodconfig kernel: :(.text+0x17e59c): undefined reference to `rpi_firmware_property' :(.text+0x17e51c): undefined reference to `rpi_firmware_get' :(.text+0x17e244): undefined reference to `rpi_firmware_property' This changes the dependency to only allow the power domain code to be enabled when the firmware driver is built-in. Other users of the firmware driver may still be loadable modules and not everyone needs the power domains, so we don't change the firmware code. Signed-off-by: Arnd Bergmann <arnd@arndb.de> | ||||
| * | ARM: bcm2835: add rpi power domain driver | Alexander Aring | 2015-12-22 | 3 | -0/+257 |
| This patch adds support for several power domains on Raspberry Pi, including USB (so it can be enabled even if the bootloader didn't do it), and graphics. This patch is the combined work of Eric Anholt (who wrote USB support inside of the Raspberry Pi firmware driver, and wrote the non-USB domain support) and Alexander Aring (who separated the original USB work out from the firmware driver).
