This makes the .write_sec()-based interface insufficient and > provoking ugly hacks. > > This patch is first step to make the driver not rely on availability of > writes to individual registers. This is achieved by refactoring the > driver to use a commit-like operation scheme: all register values are > prepared first and stored in an instance of l2x0_regs struct and then a > single callback is responsible to flush those values to the hardware. > > Signed-off-by: Tomasz Figa <t.figa@xxxxxxxxxxx> > [mszyprow: rebased onto 'ARM: l2c: use l2c_write_sec() for restoring > latency and filter regs' patch] > Signed-off-by: Marek Szyprowski <m.szyprowski@xxxxxxxxxxx> This version seems to boot just fine on am437x here: Acked-by: Tony Lindgren <tony@xxxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
