This is a note to let you know that I've just added the patch titled mips: bcm63xx: add support for clk_get_parent() to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: mips-bcm63xx-add-support-for-clk_get_parent.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit abdf7f078018cc9cedfd481478c926eeb8963139 Author: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Date: Sun Nov 14 16:42:18 2021 -0800 mips: bcm63xx: add support for clk_get_parent() [ Upstream commit e8f67482e5a4bc8d0b65d606d08cb60ee123b468 ] BCM63XX selects HAVE_LEGACY_CLK but does not provide/support clk_get_parent(), so add a simple implementation of that function so that callers of it will build without errors. Fixes these build errors: mips-linux-ld: drivers/iio/adc/ingenic-adc.o: in function `jz4770_adc_init_clk_div': ingenic-adc.c:(.text+0xe4): undefined reference to `clk_get_parent' mips-linux-ld: drivers/iio/adc/ingenic-adc.o: in function `jz4725b_adc_init_clk_div': ingenic-adc.c:(.text+0x1b8): undefined reference to `clk_get_parent' Fixes: e7300d04bd08 ("MIPS: BCM63xx: Add support for the Broadcom BCM63xx family of SOCs." ) Signed-off-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Reported-by: kernel test robot <lkp@xxxxxxxxx> Suggested-by: Russell King (Oracle) <rmk+kernel@xxxxxxxxxxxxxxx> Cc: Artur Rojek <contact@xxxxxxxxxxxxxx> Cc: Paul Cercueil <paul@xxxxxxxxxxxxxxx> Cc: linux-mips@xxxxxxxxxxxxxxx Cc: Jonathan Cameron <jic23@xxxxxxxxxx> Cc: Lars-Peter Clausen <lars@xxxxxxxxxx> Cc: linux-iio@xxxxxxxxxxxxxxx Cc: Florian Fainelli <f.fainelli@xxxxxxxxx> Cc: Andy Shevchenko <andy.shevchenko@xxxxxxxxx> Cc: Russell King <linux@xxxxxxxxxxxxxxx> Cc: bcm-kernel-feedback-list@xxxxxxxxxxxx Cc: Jonas Gorski <jonas.gorski@xxxxxxxxx> Reviewed-by: Andy Shevchenko <andy.shevchenko@xxxxxxxxx> Acked-by: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx> Acked-by: Russell King (Oracle) <rmk+kernel@xxxxxxxxxxxxxxx> Acked-by: Florian Fainelli <f.fainelli@xxxxxxxxx> Signed-off-by: Thomas Bogendoerfer <tsbogend@xxxxxxxxxxxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> diff --git a/arch/mips/bcm63xx/clk.c b/arch/mips/bcm63xx/clk.c index 637565284732d..ef268c9aac80d 100644 --- a/arch/mips/bcm63xx/clk.c +++ b/arch/mips/bcm63xx/clk.c @@ -333,6 +333,12 @@ void clk_disable(struct clk *clk) EXPORT_SYMBOL(clk_disable); +struct clk *clk_get_parent(struct clk *clk) +{ + return NULL; +} +EXPORT_SYMBOL(clk_get_parent); + unsigned long clk_get_rate(struct clk *clk) { return clk->rate;
