The s5p-cec driver has a few places that touch hdmicec clk:
static int s5p_cec_probe(struct platform_device *pdev)
{
...
cec->clk = devm_clk_get(dev, "hdmicec");
if (IS_ERR(cec->clk))
return PTR_ERR(cec->clk);
...
}
static int __maybe_unused s5p_cec_runtime_suspend(struct device *dev)
{
struct s5p_cec_dev *cec = dev_get_drvdata(dev);
clk_disable_unprepare(cec->clk);
return 0;
}
static int __maybe_unused s5p_cec_runtime_resume(struct device *dev)
{
struct s5p_cec_dev *cec = dev_get_drvdata(dev);
int ret;
ret = clk_prepare_enable(cec->clk);
if (ret < 0)
return ret;
return 0;
}
Is it ok to enable/disable clock in rusume/suspend only?
Or have I missed anything?
