    Subject[PATCH 5.16 0516/1039] mips: bcm63xx: add support for clk_set_parent()
    Date
    From: Randy Dunlap <rdunlap@infradead.org>

    [ Upstream commit 6f03055d508ff4feb8db02ba3df9303a1db8d381 ]

    The MIPS BMC63XX subarch does not provide/support clk_set_parent().
    This causes build errors in a few drivers, so add a simple implementation
    of that function so that callers of it will build without errors.

    Fixes these build errors:

    ERROR: modpost: "clk_set_parent" [sound/soc/jz4740/snd-soc-jz4740-i2s.ko] undefined!
    ERROR: modpost: "clk_set_parent" [sound/soc/atmel/snd-soc-atmel-i2s.ko] undefined!

    Fixes: e7300d04bd08 ("MIPS: BCM63xx: Add support for the Broadcom BCM63xx family of SOCs." )
