OPP: ti: Fix ti_opp_supply_probe wrong return values

2024-08-03T06:53:27Z

[ Upstream commit 3a1ac6b8f603a9310274990a0ad563a5fb709f59 ] Function ti_opp_supply_probe() since commit 6baee034cb55 ("OPP: ti: Migrate to dev_pm_opp_set_config_regulators()") returns wrong values when all goes well and hence driver probing eventually fails.

OPP: debugfs: Fix warning around icc_get_name()

2024-03-26T22:19:40Z

[ Upstream commit 28330ceb953e39880ea77da4895bb902a1244860 ] If the kernel isn't built with interconnect support, icc_get_name() returns NULL and we get following warning: drivers/opp/debugfs.c: In function 'bw_name_read': drivers/opp/debugfs.c:43:42: error: '%.62s' directive argument is null [-Werror=format-overflow=] i = scnprintf(buf, sizeof(buf), "%.62s\n", icc_get_name(path)); Fix it.

OPP: Pass rounded rate to _set_opp()

2024-02-01T00:18:49Z

commit 7269c250db1b89cda72ca419b7bd5e37997309d6 upstream. The OPP core finds the eventual frequency to set with the help of clk_round_rate() and the same was earlier getting passed to _set_opp() and that's what would get configured. The commit 1efae8d2e777 ("OPP: Make dev_pm_opp_set_opp() independent of frequency") mistakenly changed that. Fix it.

OPP: Fix argument name in doc comment

2023-08-18T05:25:49Z

The name of the argument is "opp_table" and not "table", fix the comment. Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202308172310.FzcidE4c-lkp@intel.com/ Signed-off-by: Viresh Kumar

OPP: Fix passing 0 to PTR_ERR in _opp_attach_genpd()

2023-07-24T08:01:25Z

If dev_pm_domain_attach_by_name() returns NULL, then 0 will be passed to PTR_ERR() as reported by the smatch warning below: drivers/opp/core.c:2456 _opp_attach_genpd() warn: passing zero to 'PTR_ERR' Fix it by checking for the non-NULL virt_dev pointer before passing it to PTR_ERR. Otherwise return -ENODEV. Fixes: 4ea9496cbc95 ("opp: Fix error check in dev_pm_opp_attach_genpd()") Signed-off-by: Manivannan Sadhasivam Signed-off-by: Viresh Kumar

OPP: Fix potential null ptr dereference in dev_pm_opp_get_required_pstate()

2023-07-24T08:01:17Z

"opp" pointer is dereferenced before the IS_ERR_OR_NULL() check. Fix it by removing the dereference to cache opp_table and dereference it directly where opp_table is used. This fixes the following smatch warning: drivers/opp/core.c:232 dev_pm_opp_get_required_pstate() warn: variable dereferenced before IS_ERR check 'opp' (see line 230) Fixes: 84cb7ff35fcf ("OPP: pstate is only valid for genpd OPP tables") Signed-off-by: Manivannan Sadhasivam Signed-off-by: Viresh Kumar

OPP: Update _read_freq() to return the correct frequency

OPP: Add dev_pm_opp_find_freq_exact_indexed()

2023-07-24T07:52:39Z

The indexed version of the API is added for other floor and ceil, add the same for exact as well for completeness. Signed-off-by: Viresh Kumar

OPP: Introduce dev_pm_opp_get_freq_indexed() API

2023-07-24T07:52:39Z

In the case of devices with multiple clocks, drivers need to specify the frequency index for the OPP framework to get the specific frequency within the required OPP. So let's introduce the dev_pm_opp_get_freq_indexed() API accepting the frequency index as an argument.
