Currently we are trying to enable/disable the clk of irq's gpio bank when unmask/mask irq. But the kernel's "lazy disable approach" will skip masking irq when the irq chip doesn't support irq_disable ops. So we may hit this case: irq_enable-> enable clk irq_disable-> noop irq_enable-> enable clk again irq_disable-> noop Signed-off-by: Jeffy Chen <jeffy.chen@rock-chips.com> Reviewed-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
