[PATCH v4 1/3] ARM: S5P: Add s5p_timer support for HRT

[Sangbeom Kim]

Hi Jamie,

As you said, .shift		= 32, is useless line.

And Do you mean that Is needed error handling of clk_enable  like below?

	clk_enable(timerclk);

	if (IS_ERR(timerclk)){
		clk_put(timerclk)
		panic("failed to enable timers clock");
	}

There is no another clk_enable for timerclk.
I will add clk_enable error handling code.

Thanks and regards,
S.B. Kim
