Subject: [PATCH 09/13] sun50i: A64: add support for R_I2C controller
|
|
|
|
Allwinner A64 has a I2C controller, which is in the R_ MMIO zone and has
|
|
two groups of pinmuxes on PL bank, so it's called R_I2C.
|
|
|
|
Add support for this I2C controller and the pinmux which doesn't conflict
|
|
with RSB.
