> Subject: [PATCH v4 06/13] clk: Provide struct clk for fixed rate clock > (clk_fixed_rate.c) > > Up till now the fixed rate clock ('osc') has been added to UCLASS_CLK without > declaring struct clk. As a result it was only accessible by iterating the > udevice's uclass list. > > This is a problem for clock code, which operates on pointers to struct clk > (like > clk_get_rate()), not udevices. > > After this change struct clk is accessible from udevice and udevice from > struct > clk. > > Signed-off-by: Lukasz Majewski <lu...@denx.de> > > --- > > Changes in v4: > - None > > Changes in v3: None > > drivers/clk/clk_fixed_rate.c | 5 +++++ > 1 file changed, 5 insertions(+) > > diff --git a/drivers/clk/clk_fixed_rate.c b/drivers/clk/clk_fixed_rate.c index > 50dbb13655..089f060a23 100644 > --- a/drivers/clk/clk_fixed_rate.c > +++ b/drivers/clk/clk_fixed_rate.c > @@ -8,6 +8,7 @@ > #include <dm.h> > > struct clk_fixed_rate { > + struct clk clk; > unsigned long fixed_rate; > }; > > @@ -24,10 +25,14 @@ const struct clk_ops clk_fixed_rate_ops = { > > static int clk_fixed_rate_ofdata_to_platdata(struct udevice *dev) { > + struct clk *clk = &to_clk_fixed_rate(dev)->clk; > #if !CONFIG_IS_ENABLED(OF_PLATDATA) > to_clk_fixed_rate(dev)->fixed_rate = > dev_read_u32_default(dev, "clock-frequency", 0); #endif > + /* Make fixed rate clock accessible from higher level struct clk */ > + dev->driver_data = (ulong)clk; > + clk->dev = dev; >
