2020-12-09gpio: eic-sprd: break loop when getting NULL device resourceChunyan Zhang
EIC controller have unfixed numbers of banks on different Spreadtrum SoCs, and each bank has its own base address, the loop of getting there base address in driver should break if the resource gotten via platform_get_resource() is NULL already. The later ones would be all NULL even if the loop continues.

2020-12-09pinctrl: intel: Actually disable Tx and Rx buffers on GPIO requestAndy Shevchenko
Mistakenly the buffers (input and output) become enabled together for a short period of time during GPIO request. This is problematic, because instead of initial motive to disable them in the commit af7e3eeb84e2 ("pinctrl: intel: Disable input and output buffer when switching to GPIO"), the driven value on the pin, which might be used as an IRQ line, brings firmwares of some touch pads to an awkward state that needs a full power off to recover. Fix this, as stated in the culprit commit, by disabling the buffers.

Now that ARM started following the example of arm64 and RISC-V, and no longer imposes any restrictions on the placement of the FDT in memory at boot, we no longer need per-arch implementations of efi_get_max_fdt_addr() to factor out the differences.

2020-12-09efi/efi_test: read RuntimeServicesSupportedHeinrich Schuchardt
Since the UEFI 2.8A specification the UEFI enabled firmware provides a configuration table EFI_RT_PROPERTIES_TABLE which indicates which runtime services are enabled. The EFI stub reads this table and saves the value of the field RuntimeServicesSupported internally. The Firmware Test Suite requires the value to determine if UEFI runtime services are correctly implemented. With this patch an IOCTL call is provided to read the value of the field RuntimeServicesSupported, e.g. #define EFI_RUNTIME_GET_SUPPORTED_MASK \ _IOR('p', 0x0C, unsigned int) unsigned int mask; fd = open("/dev/efi_test", O_RDWR); ret = ioctl(fd, EFI_RUNTIME_GET_SUPPORTED_MASK, &mask); Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Link: https://lore.kernel.org/r/20201127192051.1430-1-xypron.glpk@gmx.de Acked-by: Colin Ian King <colin.king@canonical.com> Acked-by: Ivan Hu <ivan.hu@canonical.com> Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
2020-12-09efi: capsule: clean scatter-gather entries from the D-cacheArd Biesheuvel
Scatter-gather lists passed to UpdateCapsule() should be cleaned from the D-cache to ensure that they are visible to the CPU after a warm reboot before the MMU is enabled. On ARM and arm64 systems, this implies a D-cache clean by virtual address to the point of coherency. However, due to the fact that the firmware itself is not able to map physical addresses back to virtual addresses when running under the OS, this must be done by the caller.

2020-12-09rtlwifi: rtl8192de: fix ofdm power compensationPing-Ke Shih
ofdm_index[] is used to indicate how many power compensation is needed to current thermal value. For internal PA module or 2.4G band, the min_index is different from other cases. This issue originally is reported by Dan. He found the size of ofdm_index[] is 2, but access index 'i' may be equal to 2 if 'rf' is 2 in case of 'is2t'. In fact, the chunk of code is added to wrong place, so move it back to proper place, and then power compensation and buffer overflow are fixed.

2020-12-09opp: Don't create an OPP table from dev_pm_opp_get_opp_table()Viresh Kumar
It has been found that some users (like cpufreq-dt and others on LKML) have abused the helper dev_pm_opp_get_opp_table() to create the OPP table instead of just finding it, which is the wrong thing to do. This routine was meant for OPP core's internal working and exposed the whole functionality by mistake. Change the scope of dev_pm_opp_get_opp_table() to only finding the table. The internal helpers _opp_get_opp_table*() are thus renamed to _add_opp_table*(), dev_pm_opp_get_opp_table_indexed() is removed (as we don't need the index field for finding the OPP table) and so the only user, genpd, is updated. Note that the prototype of _add_opp_table() was already left in opp.h by mistake when it was removed earlier and so we weren't required to add it now.

2020-12-09cpufreq: dt: Don't (ab)use dev_pm_opp_get_opp_table() to create OPP tableViresh Kumar
Initially, the helper dev_pm_opp_get_opp_table() was supposed to be used only for the OPP core's internal use (it tries to find an existing OPP table and if it doesn't find one, then it allocates the OPP table). Sometime back, the cpufreq-dt driver started using it to make sure all the relevant resources required by the OPP core are available earlier during initialization process to properly propagate -EPROBE_DEFER. It worked but it also abused the API to create an OPP table, which should be created with the help of other helpers provided by the OPP core. The OPP core will be updated in a later commit to limit the scope of dev_pm_opp_get_opp_table() to only finding an existing OPP table and not create one. This commit updates the cpufreq-dt driver before that happens. Now the cpufreq-dt driver creates the OPP and cpufreq tables for all the CPUs from driver's init callback itself.
