clk: rockchip: Add div50 clocks for px30 sdmmc, emmc,
From: Finley Xiao <finley.xiao@...> Date: Mon, 5 Mar 2018 16:17:04 +0800
Commit-Message
Some IPs, such as NAND, EMMC, SDIO and SDMMC need clock of 50% duty cycle, divfree50 can generate clock of 50% duty cycle even in odd value divisor. Signed-off-by: Finley Xiao <finley.xiao@...> Signed-off-by: Heiko Stuebner <heiko@...>
