sunxi: video: Convert panel I2C to use DM_I2C

2021-10-12T10:01:17+00:00

Two displays supported by the sunxi display driver (each one used by a single board) require initialization over I2C. Both previously used i2c_soft; replace this with the i2c-gpio instance that already exists in those boards' device trees (sun5i-a13-utoo-p66 and sun6i-a31-colombus). Since the i2c-gpio nodes are not referenced by any other node in the device trees (the device trees have no panel node), the I2C bus is selected by its node name. This panel initialization code was the only i2c_soft user, so the i2c_soft GPIO setup code can be removed now as well.

sunxi: gpio: Remove name_to_gpio macro

2021-10-11T09:46:44+00:00

This clarifies which callers must be updated to complete the DM_GPIO conversion. The only remaining caller of name_to_gpio in generic code is inside the !DM_GPIO block in cmd/gpio.c. DM_GPIO is always selected on sunxi, so that code cannot be reached. And after this commit, there are only two remaining implementations of name_to_gpio.

sunxi: Clean up inclusions of asm/arch/gpio.h

2021-10-11T09:46:44+00:00

As part of migrating to DM_GPIO and DM_PINCTRL, eventually we will remove the asm/arch/gpio.h header. In preparation, clean up the various files that include it. Some files did not contain any GPIO code at all, so this header was completely unused. A few files contained only legacy platform-specific GPIO code for setting up pin muxes. They were left unchanged, as that code will be completely removed by the DM_PINCTRL migration. The remaining files contain some combination of DM_GPIO and legacy GPIO code. For those, switch to including asm/gpio.h (if it wasn't included already). Right now, this header provides both sets of functions, because ARCH_SUNXI selects GPIO_EXTRA_HEADER. This will still be the right header to include once the DM_GPIO migration is complete and GPIO_EXTRA_HEADER is no longer needed.

video: sunxi: de2: switch to public uclass functions

2021-04-24T11:45:03+00:00

Currently DE2 driver uses functions which are defined in internal headers. They are not meant to be used outside of uclass framework. Switch DE2 driver to public ones. This has additional benefit that device_probe doesn't need to be called manually. Signed-off-by: Jernej Skrabec Reviewed-by: Andre Przywara Signed-off-by: Andre Przywara

video: sunxi: dw-hdmi: read source_id later

2021-04-24T11:44:59+00:00

There is no real need to read source_id at probe time. It also doesn't make sense to store it in driver private data since it's already stored in class platform data. While this looks like cleanup (and it is), it's also important for DE2 driver rework because this info will be filled later (after probe is already executed).

video: sunxi: Use DW-HDMI hpd function

2021-04-24T11:44:49+00:00

It turns out that there are two ways how hot plug detection can be done. One is standard way for DW HDMI controller - checking bit 2 in 0x3004 register. Another way is applicable only to Allwinner custom PHY - by checking bit 19 in register 0x10038. Both methods are equally good as far as we know. Use standard method in order to reduce amount of custom code. Reviewed-by: Andre Przywara Signed-off-by: Jernej Skrabec Signed-off-by: Andre Przywara

Currently sunxi Makefile manually specifies full path to dw-hdmi common code. However, that is not needed because it can be selected in Kconfig instead.
