Linus Walleij 5a9a567101 clk: versatile: sp810: support reentrance ... commit ec7957a6aa upstream. Despite care take to allocate clocks state containers the SP810 driver actually just supports creating one instance: all clocks registered for every instance will end up with the exact same name and __clk_init() will fail. Rename the timclken<0> .. timclken<n> to sp810_<instance>_<n> so every clock on every instance gets a unique name. This is necessary for the RealView PBA8 which has two SP810 blocks: the second block will not register its clocks unless every clock on every instance is unique and results in boot logs like this: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 0 at ../drivers/clk/versatile/clk-sp810.c:137 clk_sp810_of_setup+0x110/0x154() Modules linked in: CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.5.0-rc2-00030-g352718fc39f6-dirty #225 Hardware name: ARM RealView Machine (Device Tree Support) [<c00167f8>] (unwind_backtrace) from [<c0013204>] (show_stack+0x10/0x14) [<c0013204>] (show_stack) from [<c01a049c>] (dump_stack+0x84/0x9c) [<c01a049c>] (dump_stack) from [<c0024990>] (warn_slowpath_common+0x74/0xb0) [<c0024990>] (warn_slowpath_common) from [<c0024a68>] (warn_slowpath_null+0x1c/0x24) [<c0024a68>] (warn_slowpath_null) from [<c051eb44>] (clk_sp810_of_setup+0x110/0x154) [<c051eb44>] (clk_sp810_of_setup) from [<c051e3a4>] (of_clk_init+0x12c/0x1c8) [<c051e3a4>] (of_clk_init) from [<c0504714>] (time_init+0x20/0x2c) [<c0504714>] (time_init) from [<c0501b18>] (start_kernel+0x244/0x3c4) [<c0501b18>] (start_kernel) from [<7000807c>] (0x7000807c) ---[ end trace cb88537fdc8fa200 ]--- Cc: Michael Turquette <mturquette@baylibre.com> Cc: Pawel Moll <pawel.moll@arm.com> Fixes: 6e973d2c43 "clk: vexpress: Add separate SP810 driver" Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2016-05-11 11:21:12 +02:00
