[v5,0/4] clk: visconti: Add support common clock driver and reset driver

Message

Nobuhiro Iwamatsu Oct. 25, 2021, 3:10 a.m. UTC

Hi,

This series is PLL, clock and reset driver for Toshiba's ARM SoC,
Visconti[0].
Since the clock driver and reset driver are provided as one function,
they are
provided in cooperation with the clock driver.

This provides DT binding documentation, device driver, MAINTAINER files.

Best regards,
  Nobuhiro
