Hi,
This patchset enables spi3 clocks by marking critical clocks as CLK_IS_CRITICAL and in the meantime replaces the use of CLK_IGNORE_UNUSED for spi1 clocks.
The sclk needs to be considered critical as well.
The SPI3 in the tm2/tm2e boards will control an irled for remote controlling.
Changelog:
V1 -> V2 - the "sclk_spi3" doesn't need to be enabled in boot time as it is handled by the spi driver itself.
- use the CLK_IS_CRITICAL flag for the ioclk
V2 -> V3 - some more tests has confirmed taht "sclk_spi1,3" need to be enabled as critical!
- added Chanwoo's review in the second commit.
Thanks, Andi
