Re: [PATCH v2 17/42] ARM: at91: move at91sam9g45 SoC to new at91clk implem
From: boris brezillon
Date: Tue Jul 23 2013 - 18:35:15 EST
Le 17/07/2013 16:49, Boris BREZILLON a écrit :
This patch removes all references to the old at91 clks implementation and
make use of the new at91 clk implem for at91sam9g45 SoC.
All dt specific lookups are removed (handled in clk device tree binding).

There is a bug here. It should be:
clk = at91_clk_register_peripheral(aestdessha_clk_lookup[0].con_id,
"mck", AT91SAM9G45_ID_AESTDESSHA);
+ for (k = 0; k < ARRAY_SIZE(aestdessha_clk_lookup); k++)
+ aestdessha_clk_lookup[k].clk = clk;
+ clkdev_add_table(vdec_clk_lookup,
+ ARRAY_SIZE(aestdessha_clk_lookup));
Same bug here:
clkdev_add_table(aestdessha_clk_lookup, ARRAY_SIZE(aestdessha_clk_lookup));
These bugs will be fixed in next version.
