2019-08-07clk: st: clk-flexgen: Add of_node_put() in st_of_flexgen_setup()Nishka Dasgupta1-0/+1
In function st_of_flexgen_setup, variable pnode takes the return value of of_get_parent, which gets a node but does not put it. If pnode is not put before the function returns, it may cause a memory leak. Hence put pnode after its last occurrence. Issue found with Coccinelle.

2015-02-18clk: Replace explicit clk assignment with __clk_hw_set_clkJavier Martinez Canillas1-10/+10
The change in the clk API to return a per-user clock instance, moved the clock state to struct clk_core so now the struct clk_hw .core field is used instead of .clk for most operations. So for hardware clocks that needs to share the same clock state, both the .core and .clk pointers have to be assigned but currently only the .clk is set. This leads to NULL pointer dereference when the operations try to access the hw clock .core. For example, the composite clock rate and mux components didn't have a .core set which leads to this error: Unable to handle kernel NULL pointer dereference at virtual address 00000034 pgd = c0004000 [00000034] *pgd=00000000 Internal error: Oops: 5 [#1] PREEMPT SMP ARM Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.19.0-next-20150211-00002-g1fb7f0e1150d #423 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) task: ee480000 ti: ee488000 task.ti: ee488000 PC is at clk_mux_determine_rate_flags+0x14/0x19c LR is at __clk_mux_determine_rate+0x24/0x2c pc : [<c03a355c>] lr : [<c03a3734>] psr: a0000113 sp : ee489ce8 ip : ee489d84 fp : ee489d84 r10: 0000005c r9 : 00000001 r8 : 016e3600 r7 : 00000000 r6 : 00000000 r5 : ee442200 r4 : ee440c98 r3 : ffffffff r2 : 00000000 r1 : 016e3600 r0 : ee440c98 Flags: NzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment kernel Control: 10c5387d Table: 4000406a DAC: 00000015 Process swapper/0 (pid: 1, stack limit = 0xee488210) Stack: (0xee489ce8 to 0xee48a000) 9ce0: 00000000 ffffffff 60000113 ee440c98 ee442200 00000000 9d00: 016e3600 ffffffff 00000001 0000005c ee489d84 c03a3734 ee489d80 ee489d84 9d20: 00000000 c048b130 00000400 c03a5798 ee489d80 ee489d84 c0607f60 ffffffea 9d40: 00000001 00000001 ee489d5c c003f844 c06e3340 ee402680 ee440d0c ed935000 9d60: 016e3600 00000003 00000001 0000005c eded3700 c03a11a0 ee489d80 ee489d84 9d80: 016e3600 ee402680 c05b413a eddc9900 016e3600 c03a1228 00000000 ffffffff 9da0: ffffffff eddc9900 016e3600 c03a1c1c ffffffff 016e3600 ed8c6710 c03d6ce4 9dc0: eded3400 00000000 00000000 c03c797c 00000001 0000005c eded3700 eded3700 9de0: 000005e0 00000001 0000005c c03db8ac c06e7e54 c03c8f08 00000000 c06e7e64 9e00: c06b6e74 c06e7f64 000005e0 c06e7df8 c06e5100 00000000 c06e7e6c c06e7f54 9e20: 00000000 00000000 eebd9550 00000000 c06e7da0 c06e7e54 ee7b5010 c06e7da0 9e40: eddc9690 c06e7db4 c06b6e74 00000097 00000000 c03d4398 00000000 ee7b5010 9e60: eebd9550 c06e7da0 00000000 c03db824 ee7b5010 fffffffe c06e7db4 c0299c7c 9e80: ee7b5010 c072a05c 00000000 c0298858 ee7b5010 c06e7db4 ee7b5044 00000000 9ea0: eddc9580 c0298a04 c06e7db4 00000000 c0298978 c02971d4 ee405c78 ee732b40 9ec0: c06e7db4 eded3800 c06d6738 c0298044 c0608300 c06e7db4 00000000 c06e7db4 9ee0: 00000000 c06beb58 c06beb58 c0299024 00000000 c068dd00 00000000 c0008944 9f00: 00000038 c049013c ee462200 c0711920 ee480000 60000113 c06c2cb0 00000000 9f20: 00000000 c06c2cb0 60000113 00000000 ef7fcafc 00000000 c0640194 c00389ec 9f40: c05ec3a8 c063f824 00000006 00000006 c06c2c50 c0696444 00000006 c0696424 9f60: c06ee1c0 c066b588 c06b6e74 00000097 00000000 c066bd44 00000006 00000006 9f80: c066b588 c003d684 00000000 c0481938 00000000 00000000 00000000 00000000 9fa0: 00000000 c0481940 00000000 c000e680 00000000 00000000 00000000 00000000 9fc0: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 9fe0: 00000000 00000000 00000000 00000000 00000013 00000000 00000000 00000000 [<c03a355c>] (clk_mux_determine_rate_flags) from [<c03a3734>] (__clk_mux_determine_rate+0x24/0x2c) [<c03a3734>] (__clk_mux_determine_rate) from [<c03a5798>] (clk_composite_determine_rate+0xbc/0x238) [<c03a5798>] (clk_composite_determine_rate) from [<c03a11a0>] (clk_core_round_rate_nolock+0x5c/0x9c) [<c03a11a0>] (clk_core_round_rate_nolock) from [<c03a1228>] (__clk_round_rate+0x38/0x40) [<c03a1228>] (__clk_round_rate) from [<c03a1c1c>] (clk_round_rate+0x20/0x38) [<c03a1c1c>] (clk_round_rate) from [<c03d6ce4>] (max98090_dai_set_sysclk+0x34/0x118) [<c03d6ce4>] (max98090_dai_set_sysclk) from [<c03c797c>] (snd_soc_dai_set_sysclk+0x38/0x80) [<c03c797c>] (snd_soc_dai_set_sysclk) from [<c03db8ac>] (snow_late_probe+0x24/0x48) [<c03db8ac>] (snow_late_probe) from [<c03c8f08>] (snd_soc_register_card+0xf04/0x1070) [<c03c8f08>] (snd_soc_register_card) from [<c03d4398>] (devm_snd_soc_register_card+0x30/0x64) [<c03d4398>] (devm_snd_soc_register_card) from [<c03db824>] (snow_probe+0x68/0xcc) [<c03db824>] (snow_probe) from [<c0299c7c>] (platform_drv_probe+0x48/0x98) [<c0299c7c>] (platform_drv_probe) from [<c0298858>] (driver_probe_device+0x114/0x234) [<c0298858>] (driver_probe_device) from [<c0298a04>] (__driver_attach+0x8c/0x90) [<c0298a04>] (__driver_attach) from [<c02971d4>] (bus_for_each_dev+0x54/0x88) [<c02971d4>] (bus_for_each_dev) from [<c0298044>] (bus_add_driver+0xd8/0x1cc) [<c0298044>] (bus_add_driver) from [<c0299024>] (driver_register+0x78/0xf4) [<c0299024>] (driver_register) from [<c0008944>] (do_one_initcall+0x80/0x1d0) [<c0008944>] (do_one_initcall) from [<c066bd44>] (kernel_init_freeable+0x10c/0x1d8) [<c066bd44>] (kernel_init_freeable) from [<c0481940>] (kernel_init+0x8/0xe4) [<c0481940>] (kernel_init) from [<c000e680>] (ret_from_fork+0x14/0x34) Code: e24dd00c e5907000 e1a08001 e88d000c (e5970034) The changes were made using the following cocinelle semantic patch: @i@ @@ @depends on i@ identifier dst;

2015-01-20clk: st: STiH410: Fix pdiv and fdiv divisor when setting ratePeter Griffin1-4/+15
Debugging eMMC on upstream kernels it has been noticed that when the targetpack configures MMC0 clock to 200Mhz (required to switch to HS200) then everything works OK. However if the kernel sets the clock rate using clk_set_rate, then the eMMC card initialisation fails with timeouts. Lower clock speeds (the default being 50Mhz) work ok, but they we fail to get good eMMC transfer rates. Looking through the vendor kernel clock driver reveals Giuseppe had already fixed this issue, but the patch hasn't made its way upstream. The issue is fixed by changing the logic to manage the pdiv and fdiv divisors used for setting the rate inside the flexgen driver code. Pdiv is mainly targeted for low freq results, while fdiv should be used for divs =< 64. The other way can lead to 'duty cycle' issues. I have changed the original patch to keep the original behaviour in cases where the div is >64 which matches the original comment and patch description more closely. Although no clocks appear to hit this case currently when booting an upstream kernel.

2014-07-28clk: st: STiH407: Support for Flexgen ClocksGabriel FERNANDEZ1-0/+331
This patch is the Flexgen implementation reusing as much as possible of Common Clock Framework functions. The idea is to have an instance of "struct flexgen" per output clock. It represents the clock cross bar (by a mux element), and the pre and final dividers (using dividers and gates elements).
