soc: mediatek: pwrap: Zero initialize rdata in pwrap_init_cipher

2019-06-22T06:18:20Z

[ Upstream commit 89e28da82836530f1ac7a3a32fecc31f22d79b3e ] When building with -Wsometimes-uninitialized, Clang warns: drivers/soc/mediatek/mtk-pmic-wrap.c:1358:6: error: variable 'rdata' is used uninitialized whenever '||' condition is true [-Werror,-Wsometimes-uninitialized] If pwrap_write returns non-zero, pwrap_read will not be called to initialize rdata, meaning that we will use some random uninitialized stack value in our print statement. Zero initialize rdata in case this happens.

soc: Mediatek: Enable SCPSYS power domain driver by default

2015-11-24T18:15:38Z

If enable Mediatek 8173 SoC, it should also enable power domain driver. Otherwise access clk subsystem register will fail. Signed-off-by: Eddie Huang Acked-by: Matthias Brugger Signed-off-by: Kevin Hilman

soc: mediatek: Fix random hang up issue while kernel init

2015-10-14T13:34:43Z

In kernel late init, it turns off all unused clocks, which needs to access subsystem registers such as VENC and VENC_LT. Accessing MT8173 VENC registers needs two top clocks, mm_sel and venc_sel. Accessing VENC_LT registers needs mm_sel and venclt_sel. So we need to keep these clocks on before accessing their registers. This patch keeps venc_sel / venclt_sel clock on when VENC / VENC_LT's power is on, to prevent system hang up while accessing its registeres. Signed-off-by: James Liao Signed-off-by: Matthias Brugger

soc: mediatek: add scpsys support active_wakeup

2015-09-27T13:18:33Z

Register gpd_dev_ops.active_wakeup function to support keep power during suspend state. And add flag to each power domain to decide whether keep power during suspend or not.

soc: mediatek: Move the initial setting of pmic wrap interrupt before requesting irq.

2015-09-27T11:56:08Z

The watchdog may not be initialized by the bootloader, even if the rest of the pwrap is. Move the watchdog initialization out of pwrap_init() to make sure the watchdog is always initialized and not only when the pwrap is uninitialized.

soc: mediatek: Fix SCPSYS compilation

SCPSYS driver misses the module.h include which makes it fail when compiling with allmodconf. This patch fixes this. Signed-off-by: Matthias Brugger Acked-by: Sascha Hauer Signed-off-by: Olof Johansson

soc: Mediatek: Add SCPSYS power domain driver

2015-07-06T16:36:32Z

This adds a power domain driver for the Mediatek SCPSYS unit. The System Control Processor System (SCPSYS) has several power management related tasks in the system. The tasks include thermal measurement, dynamic voltage frequency scaling (DVFS), interrupt filter and lowlevel sleep control. The System Power Manager (SPM) inside the SCPSYS is for the MTCMOS power domain control. For now this driver only adds power domain support, the more advanced features are not yet supported. The driver implements the generic PM domain device tree bindings, the first user will most likely be the Mediatek AFE audio driver.

soc: mediatek: Add infracfg misc driver support

2015-07-06T16:36:31Z

This adds support for some miscellaneous bits of the infracfg controller. The mtk_infracfg_set/clear_bus_protection functions are necessary for the scpsys power domain driver to handle the bus protection bits which are contained in the infacfg register space.

soc: mediatek: Add compile dependency to pmic-wrapper

2015-05-27T14:27:05Z

The pmic-wrapper calls the reset controller. If CONFIG_RESET_CONTROLLER is not set, compilation fails with: drivers/soc/mediatek/mtk-pmic-wrap.c: In function ‘pwrap_probe’: drivers/soc/mediatek/mtk-pmic-wrap.c:836:2: error: implicit declaration of function ‘devm_reset_control_get’ [-Werror=implicit-function-declaration] This patch sets the dependency in the Kconfig file.
