soc: mediatek: mtk-mutex: Reduce type size for mtk_mutex_data members

2024-07-30T08:58:46+00:00

All of mutex_mod and mutex_table_mod contain an array of bit
numbers, which can go from 0 to 63, it is hence not needed to
use an unsigned 32-bits integer to store that: change them to
unsigned 8-bits instead.

As for the mutex_sof table since this directly contains the values
to write to the DISP_MUTEXn_CTL register, which has only bits [13:0]
(so this register is effectively 14 bits long), change that to use
unsigned 16-bits.

The type of mutex_{mod,sof}_reg was also changed to 16 bits, as
the maximum value that those will ever have is 0x800, because it
calculates as 0x30 + (0x20 * n) where n's maximum value is 63.

This reduces module size and brings no functional changes.

soc: mediatek: pwrap: Use devm_clk_bulk_get_all_enable()

2024-07-30T08:57:20+00:00

Use devm_clk_bulk_get_all_enable() to simplify the code and to make sure
that clk_disable_unprepare() is called if the driver is unloaded.

2024-06-28T16:41:00+00:00

MediaTek driver updates for v6.11

This adds the previously missed Tone Curve Conversion (TCC)
MuteX bit to enable the same in MDP3 on the the MT8188 SoC,
disables 9-bit Alpha for display HDR support in MT8195 and
adds math operation support in the Global Command Engine for
all MediaTek SoCs, which will be used in the near future in
the ISP driver.

soc: mtk-cmdq: Add cmdq_pkt_logic_command to support math operation

2024-06-27T10:41:51+00:00

Add cmdq_pkt_logic_command to support math operation.

cmdq_pkt_logic_command can append logic command to the CMDQ packet,
ask GCE to execute a arithmetic calculate instruction,
such as add, subtract, multiply, AND, OR and NOT, etc.

Note that all arithmetic instructions are unsigned calculations.
If there are any overflows, GCE will sent the invalid IRQ to notify
CMDQ driver.

soc: mediatek: Disable 9-bit alpha in ETHDR

2024-06-27T10:41:51+00:00

When 9-bit alpha is enabled, its value will be converted from 0-255 to
0-256 (255 = not defined). This is designed for special HDR related
calculation, which should be disabled by default, otherwise, alpha
blending will not work correctly.

Pull SoC driver updates from Arnd Bergmann:
 "As usual, these are updates for drivers that are specific to certain
  SoCs or firmware running on them.

  Notable updates include

   - The new STMicroelectronics STM32 "firewall" bus driver that is used
     to provide a barrier between different parts of an SoC

   - Lots of updates for the Qualcomm platform drivers, in particular
     SCM, which gets a rewrite of its initialization code

   - Firmware driver updates for Arm FF-A notification interrupts and
     indirect messaging, SCMI firmware support for pin control and
     vendor specific interfaces, and TEE firmware interface changes
     across multiple TEE drivers

   - A larger cleanup of the Mediatek CMDQ driver and some related bits

   - Kconfig changes for riscv drivers to prepare for adding Kanaan k230
     support

   - Multiple minor updates for the TI sysc bus driver, memory
     controllers, hisilicon hccs and more"
