I find 33 "select COMMON_CLK" and > 18 "depends on COMMON_CLK". In drivers/ I count 12 select COMMON_CLK vs. 37 depends on COMMON_CLK Do I need new glasses? :-) With MMC_SDHCI_OF_ARASAN being the only one of all of them we're using on Rockchip platforms. I vaguely remember depends being preferred over select in general, so you don't enable large parts by accident or cause some select chains - but I may be wrong. > Either case > > Reviewed-by: Guenter Roeck <linux at roeck-us.net> for me as well: Reviewed-by: Heiko Stuebner <heiko at sntech.de> > > > select GENERIC_PHY > > help > > > > Support for Rockchip USB2.0 PHY with Innosilicon IP block.
