2022-06-30clk: qcom: gcc-sc8280xp: use phy-mux clock for PCIeJohan Hovold1-90/+31
Use the new phy-mux clock implementation for the PCIe pipe clock muxes so that the pipe clock source is set to the QMP PHY PLL when the downstream pipe clock is enabled and restored to the always-on XO when it is again disabled. This is needed to prevent the corresponding GDSC from hanging when enabling or disabling the PCIe power domain, something which requires a ticking source.

Access to I/O of SM8250 camera clock controller IP depends on enabled GCC_CAMERA_AHB_CLK clock supplied by global clock controller, the latter one is inited on subsys level, so, to satisfy the dependency, it would make sense to deprive the init level of camcc-sm8250 driver.

2022-06-26clk: qcom: regmap: add PHY clock source implementationDmitry Baryshkov3-0/+96
On recent Qualcomm platforms the QMP PIPE clocks feed into a set of muxes which must be parked to the "safe" source (bi_tcxo) when corresponding GDSC is turned off and on again. Currently this is handcoded in the PCIe driver by reparenting the gcc_pipe_N_clk_src clock. However the same code sequence should be applied in the pcie-qcom endpoint, USB3 and UFS drivers. Rather than copying this sequence over and over again, follow the example of clk_rcg2_shared_ops and implement this parking in the enable() and disable() clock operations. Supplement the regmap-mux with the new clk_regmap_phy_mux type, which implements such multiplexers as a simple gate clocks. This is possible since each of these multiplexers has just two clock sources: one coming from the PHY and a reference (XO) one. If the clock is running off the from-PHY source, report it as enabled. Report it as disabled otherwise (if it uses reference source). This way the PHY will disable the pipe clock before turning off the GDSC, which in turn would lead to disabling corresponding pipe_clk_src (and thus it being parked to a safe, reference clock source). And vice versa, after enabling the GDSC the PHY will enable the pipe clock, which would cause pipe_clk_src to be switched from a safe source to the working one.

2022-06-06bluetooth: don't use bitmaps for random flag accessesLinus Torvalds5-39/+27
The bluetooth code uses our bitmap infrastructure for the two bits (!) of connection setup flags, and in the process causes odd problems when it converts between a bitmap and just the regular values of said bits. It's completely pointless to do things like bitmap_to_arr32() to convert a bitmap into a u32. It shoudln't have been a bitmap in the first place. The reason to use bitmaps is if you have arbitrary number of bits you want to manage (not two!), or if you rely on the atomicity guarantees of the bitmap setting and clearing. The code could use an "atomic_t" and use "atomic_or/andnot()" to set and clear the bit values, but considering that it then copies the bitmaps around with "bitmap_to_arr32()" and friends, there clearly cannot be a lot of atomicity requirements. So just use a regular integer. In the process, this avoids the warnings about erroneous use of bitmap_from_u64() which were triggered on 32-bit architectures when conversion from a u64 would access two words (and, surprise, surprise, only one word is needed - and indeed overkill - for a 2-bit bitmap). That was always problematic, but the compiler seems to notice it and warn about the invalid pattern only after commit 0a97953fd221 ("lib: add bitmap_{from,to}_arr64") changed the exact implementation details of 'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

2022-06-05modpost: simplify mod->name allocationMasahiro Yamada1-13/+12
mod->name is set to the ELF filename with the suffix ".o" stripped. The current code calls strdup() and free() to manipulate the string, but a simpler approach is to pass new_module() with the name length subtracted by 2. Also, check if the passed filename ends with ".o" before stripping it. The current code blindly chops the suffix: tmp[strlen(tmp) - 2] = '\0' It will cause buffer under-run if strlen(tmp) < 2; Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nick Desaulniers <ndesaulniers@google.com>
2022-06-05kbuild: factor out the common objtool argumentsMasahiro Yamada4-97/+52
scripts/Makefile.build and scripts/link-vmlinux.sh have similar setups for the objtool arguments. It was difficult to factor out them because all the vmlinux build rules were written in a shell script. It is somewhat tedious to touch the two files every time a new objtool option is supported. To reduce the code duplication, move the objtool for vmlinux.o into scripts/Makefile.vmlinux_o. Then, move the common macros to Makefile.lib so they are shared between Makefile.build and Makefile.vmlinux_o.
