The schema for "qcom,tcs-config" property can be a little bit simpler, without the need of defining each item. Also move the description of each part of "qcom,tcs-config" tupple to the tupple items description. Suggested-by:

MSM8909 is a fairly old 32-bit SoC without PSCI support, so the additional CPU cores need to be initialized with a custom enable-method. Fortunately it works just like on MSM8226 and MSM8916 so just add an additional compatible as alias to the DT schema. Signed-off-by:

Given the lack of public documentation for the SPM, the configuration data is taken without modification from Qualcomm's msm-3.10 release [1]. It is pretty much identical to the one for MSM8916, except that 0x3B is missing in the sequence for standalone power collapse for some reason.

Bandwidth monitoring (BWMON) sits between various subsytems like CPU, GPU, Last Level caches and memory subsystem. The BWMON can be configured to monitor the data throuhput between memory and other subsytems. The throughput is measured within specified sampling window and is used to vote for corresponding interconnect bandwidth. Current implementation brings support for BWMON v4, used for example on SDM845 to measure bandwidth between CPU (gladiator_noc) and Last Level Cache (memnoc). Usage of this BWMON allows to remove fixed bandwidth votes from cpufreq (CPU nodes) thus achieve high memory throughput even with lower CPU frequencies. The driver was tested on SDM845.

Commit ac0126a0 ("soc: qcom: cmd-db: replace strncpy() with strscpy_pad()") breaks booting on my sc7280-herobrine-herobrine device. From printouts I see that at bootup the function is called with an id of "lnbclka2" which is 8 bytes big. Previously all 8 bytes of this string were copied to the destination. Now only 7 bytes will be copied since strscpy_pad() saves a byte for '\0' termination. We don't need the '\0' termination in the destination. Let's go back to strncpy(). According to the warning: If a caller is using non-NUL-terminated strings, strncpy() can still be used, but destinations should be marked with the __nonstring attribute to avoid future compiler warnings. ...so we'll do that. While we're at it, let's change the query array to use "sizeof(ent->id)" so it can't possibly go out of sync with our later copy.

Some sc7180 Chromebooks actually have sc7180P (known by many names, apparently, including possibly sc7180 Pro and sc7185). This is a sc7180 part that has slightly higher clock speeds. The official ID number allocated to these devices by Qualcomm is 495 so we'll add an entry to the table for them. Note that currently shipping BIOS for these devices will actually end up reporting an ID of 407 due to a bug but eventually a new BIOS will be released which corrects it to 495. Signed-off-by:

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 0a97953f ("lib: add bitmap_{from,to}_arr64") changed the exact implementation details of 'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.
