From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ben Dooks Date: Mon, 31 Mar 2014 17:47:27 +0000 Subject: [PATCH] clk: shmobile: fix setting paretn clock rate Message-Id: <1396288047-6647-1-git-send-email-ben.dooks@codethink.co.uk> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-arm-kernel@lists.infradead.org If the driver needs to change a clock rate, then it must be propogated through the MSTP clock to the parent clock (such as shdi0 -> sd0). Without this we cannot up-rate default clocks which are really slow (such as the mmcif1 which defaults to 12MHz where it could be running at 97MHz) Signed-off-by: Ben Dooks --- drivers/clk/shmobile/clk-mstp.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/clk/shmobile/clk-mstp.c b/drivers/clk/shmobile/clk-mstp.c index 7bfdcfc..9fc754b 100644 --- a/drivers/clk/shmobile/clk-mstp.c +++ b/drivers/clk/shmobile/clk-mstp.c @@ -139,7 +139,7 @@ cpg_mstp_clock_register(const char *name, const char *parent_name, init.name = name; init.ops = &cpg_mstp_clock_ops; - init.flags = CLK_IS_BASIC; + init.flags = CLK_IS_BASIC | CLK_SET_RATE_PARENT; init.parent_names = &parent_name; init.num_parents = 1; -- 1.9.0
