There was two remaining defines which weren't properly aligned with the rest. Align them improving readability. Signed-off-by:

Update kernel doc for mtk_data and also remove no needed documentation for mtk_gc which is clear enough to don't need it. Signed-off-by:

PIN_MASK macro was being used because of the fact we were only using one interrupt controller for all of the gpio chips. This has been changed to use one per gpio chip and each has 32 irqs. Because of this this macro is not needed anymore. Use BIT macro instead. Signed-off-by:

Instead of create a custom irq_domain for this chip, use 'gpiochip_set_chained_irqchip' from GPIOLIB_IRQCHIP. It is ok to call this function several times. We have to manually mark the line with 'IRQF_SHARED' and then loop over the three banks until you find a hit. There were some problems with removing an irqchip like that but this driver is a bool so it might work just fine. After this changes the functions 'mediatek_gpio_to_irq' is not needed anymore and also the 'gpio_irq_domain' field from the state container. Instead of use the custom irq domain in the irq handler use the associated domain from the gpio_chip in 'irq_find_mapping' function. Function 'mediatek_gpio_bank_probe' has been moved a it to the botton to have all the irq related functions together and avoid some forward declarations to resolve some symbols along the code.

This chip support high level and low level interrupts. Those have to be implemented also to get a complete and clean driver. Signed-off-by:

This driver is actually platform-agnostic. Add COMPILE_TEST for the compilation test coverage. Signed-off-by:

When implementing custom irqchips it is important to also implement .irq_request_resources() and .irq_release_resources() and make sure these call gpiochip_[un]lock_as_irq(). Add those two for this driver. Also store struct device pointer in global state structure to be able to use 'dev_err' with the device from 'mediatek_request_resources' function. Signed-off-by:

This driver was being registered using 'module_platform_driver' but it is not a module at all. Instead of this use 'builtin_platform_driver' which seems to be the correct one. Signed-off-by:

Including file '<linux/gpio.h>' should be avoided in new drivers code, so just remove it because it is no necessary at all. Signed-off-by:

Gpio complexity is just masking the fact that offset is always 0..n and writes to bits 0..n of some memory address. Because of this whole thing can just me converted to use GPIO_GENERIC and avoid duplications of a lot of driver custom functions. So use bgpio_init instead of custom code adding GPIO_GENERIC dependency to the Kconfig file. Also to make easier using bgpio_init function offset for each gpio bank, enumeration where register were defined has been replaced in favour of some macros which handle each gpio offset taking into account the bank where are located. Because of this change write and read functions which are being used for remaining irq handling stuff have been updated also as well as its dependencies along the code. Signed-off-by:

The response type of the SD_APP_OP_COND command is correctly determined using the mmc_resp_type macro, because the only use of that opcode, mmc_send_app_op_cond, correctly places MMC_RSP_R3 in cmd.flags. So there is no need to treat that opcode separately. Signed-off-by:

Currently the base address for all io operations is hidden behind a macro, REG_ADD. This macro uses the symbol "base" as the base address and all functions set base = host->base. This is hard to read, so the whole wrapping is removed and host->base is directly inserted in the io access. Signed-off-by:

In the current code, msdc_clr_fifo is a macro and just busy waits for a limited amount of time for the fifo clear to finish. That is not correct, the programming manual hits, that the user should wait until the bit is cleared by hardware and not a limited amount of time. So the code is changed to a function, that also relaxes the cpu while busy waiting. Signed-off-by:

The BUG_ON() removed by this patch is just a duplicate of a prior BUG_ON() statement. There the condition is just clearer, it checks weather sglen > MAX_BD_NUM and MAX_BD_NUM is equal MAX_BD_PER_GPD. So this statement can be safely removed. Signed-off-by:

Current code uses two functions for dma setup, msdc_dma_config and msdc_dma_setup. By now msdc_dma_setup is nearly empty and mainly calls msdc_dma_config, so the later one can be inline into the first one. While doing this there is also some refactoring done. Signed-off-by:
