With a proper fix for Kirkwood ethernet IP MAC address clock gating issue, we can now remove the clock gating workaround that always enabled ethernet clocks.
Signed-off-by: Sebastian Hesselbarth <[email protected]> --- Changelog: v2->v3: - make use of new public clk_is_enabled, adds dependency to [1] - add warning about gated clock && missing MAC property (Suggested by Jason Gunthorpe) v1->v2: - check for gated clock before accessing eth registers (Suggested by Andrew Lunn) [1] http://www.spinics.net/lists/arm-kernel/msg277392.html Cc: Jason Cooper <[email protected]> Cc: Andrew Lunn <[email protected]> Cc: Russell King <[email protected]> Cc: Grant Likely <[email protected]> Cc: Benjamin Herrenschmidt <[email protected]> Cc: Jason Gunthorpe <[email protected]> Cc: Ezequiel Garcia <[email protected]> Cc: Mike Turquette <[email protected]> Cc: [email protected] Cc: [email protected] --- arch/arm/mach-kirkwood/board-dt.c | 14 -------------- 1 file changed, 14 deletions(-) diff --git a/arch/arm/mach-kirkwood/board-dt.c b/arch/arm/mach-kirkwood/board-dt.c index 28e952b..6925de8 100644 --- a/arch/arm/mach-kirkwood/board-dt.c +++ b/arch/arm/mach-kirkwood/board-dt.c @@ -41,7 +41,6 @@ static void __init kirkwood_legacy_clk_init(void) struct device_node *np = of_find_compatible_node( NULL, NULL, "marvell,kirkwood-gating-clock"); struct of_phandle_args clkspec; - struct clk *clk; clkspec.np = np; clkspec.args_count = 1; @@ -53,19 +52,6 @@ static void __init kirkwood_legacy_clk_init(void) clkspec.args[0] = CGC_BIT_PEX1; orion_clkdev_add("1", "pcie", of_clk_get_from_provider(&clkspec)); - - /* - * The ethernet interfaces forget the MAC address assigned by - * u-boot if the clocks are turned off.
