[U-Boot] [PATCH 0/4] sunxi: i2c: Add DM I2C support for A64/H3/H5

[U-Boot] [PATCH 0/4] sunxi: i2c: Add DM I2C support for A64/H3/H5

[Jernej Skrabec]

This series implements DM I2C support, but allows old I2C to be selected
when needed.

Patch 1 makes sure that sy8106a driver is compiled only during SPL build.

Patch 2 moves i2c_init_board() function to more convenient place for
follow up patch. It doens't do any functional change.

Patch 3 introduces DM I2C support for sun6i-a31 compatible I2C
controllers.

Patch 4 enables DM I2C only for A64/H3/H5. Other platforms would easily
support DM I2C too, but their PMIC drivers needs to be ported to DM in
order not to lose any existing functionality.

Best regards,
Jernej Skrabec

[U-Boot] [PATCH 1/4] sunxi: power: Compile sy8106a driver only during SPL build

[Jernej Skrabec]

Driver for that regulator is used only in SPL and it uses old I2C
interface. If we want to use DM I2C in U-Boot proper, compilation of
this driver has to be limited only to SPL.

[U-Boot] [PATCH 2/4] sunxi: Move function for later convenience

[Jernej Skrabec]

This commit only moves i2c_init_board() function almost to the top and
doesn't have any functional changes.

This is needed for a temporary workaround in next commit when support
for DM I2C will be introduced.

[U-Boot] [PATCH 3/4] sunxi: i2c: Add support for DM I2C

[Jernej Skrabec]

This commit adds support for DM I2C on sunxi platform. It can coexist
with old style sunxi I2C driver, because it is still used in SPL and
by some SoCs.

Because sunxi platform doesn't yet support DM clk, reset and pinctrl
driver, workaround is needed to enable clocks and set resets and
pinctrls. This is done by calling i2c_init_board() in board_init().
This means that CONFIG_I2Cx_ENABLE options needs to be correctly set
in order to use needed I2C controller.

Commit is based on the previous patch made by Philipp Tomsich

[U-Boot] [PATCH 4/4] sunxi: Enable DM_I2C for A64/H3/H5

[Jernej Skrabec]

This commits enable DM I2C support for A64/H3/H5 SoCs.

It is not enabled globaly for all sunxi SoCs, because some boards use
PMICs which are connected through I2C. In order to keep same
functionality, PMIC drivers needs to be ported to DM too.

Do you want to pick up this patchset?

Or should I push it through u-boot-i2c?
If so, please add your Ack or Review tag, thanks!
