clk: ti: dra7-atl: Fix leak of of_nodes

2024-11-08T15:20:31Z

[ Upstream commit 9d6e9f10e2e031fb7bfb3030a7d1afc561a28fea ] This fix leaking the of_node references in of_dra7_atl_clk_probe(). The docs for of_parse_phandle_with_args() say that the caller must call of_node_put() on the returned node. This adds the missing of_node_put() to fix the leak.

clk: ti: dra7-atl: Fix reference leak in of_dra7_atl_clk_probe

[ Upstream commit 9c59a01caba26ec06fefd6ca1f22d5fd1de57d63 ] pm_runtime_get_sync() will increment pm usage counter. Forgetting to putting operation will result in reference leak. Add missing pm_runtime_put_sync in some error paths.

clocksource/drivers/timer-ti-dm: Handle dra7 timer wrap errata i940

2021-06-23T12:41:31Z

commit 25de4ce5ed02994aea8bc111d133308f6fd62566 upstream. There is a timer wrap issue on dra7 for the ARM architected timer. In a typical clock configuration the timer fails to wrap after 388 days. To work around the issue, we need to use timer-ti-dm percpu timers instead. Let's configure dmtimer3 and 4 as percpu timers by default, and warn about the issue if the dtb is not configured properly. For more information, please see the errata for "AM572x Sitara Processors Silicon Revisions 1.1, 2.0": https://www.ti.com/lit/er/sprz429m/sprz429m.pdf The concept is based on earlier reference patches done by Tero Kristo and Keerthy.

clk: ti: am33xx: fix RTC clock parent

2020-06-03T06:21:13Z

[ Upstream commit dc6dbd51009fc412729c307161f442c0a08618f4 ] Right now, trying to use RTC purely with the ti-sysc / clkctrl framework fails to enable the RTC module properly. Based on experimentation, this appears to be because RTC is sourced from the clkdiv32k optional clock. TRM is not very clear on this topic, but fix the RTC to use the proper source clock nevertheless.
