2020-10-01spi: spi-mtk-nor: add helper for checking prg mode opsChuanhong Guo
op checking/resizing logic for the newly added mtk_nor_spi_mem_prg is more complicated. Add two helper functions for them: mtk_nor_match_prg: check whether an op is supported by prg mode. mtk_nor_adj_prg_size: adjust data size for mtk_nor_spi_mem_prg. mtk_nor_match_prg isn't called yet because supports_op is currently broken. It'll be used in the next fix commit.

2020-10-01spi: spi-mtk-nor: make use of full capability of prg modeChuanhong Guo
"program" mode on this controller can trigger up to 56 bits of data shifting. During the operation, data in PRGDATA[0-5] will be shifted out from MOSI, and data from MISO will be continuously filling SHREG[0-9]. Currently this mode is used to implement transfer_one_message for 6-byte full-duplex transfer, but it can execute a transfer for up-to 7 bytes as long as the last byte is read only. transfer_one_message is expected to perform full-duplex transfer, instead of transfer with specific format. mtk_nor_spi_mem_prg is added here to use this extra byte. Newer version of this controller can trigger longer data shifting with shift bytes more than PRGDATA_MAX + SHREG_MAX. This patch is implemented with that in mind and it checks against both SHREG_MAX and PRG_CNT_MAX for future support of new controllers.

2020-10-02tpm_tis: Add a check for invalid statusJames Bottomley
Some TIS based TPMs can return 0xff to status reads if the locality hasn't been properly requested. Detect this condition by checking the bits that the TIS spec specifies must return zero are clear and return zero in that case. Also drop a warning so the problem can be identified in the calling path and fixed (usually a missing try_get_ops()).

When fitted, the SynQuacer platform exposes its SPI TPM via a MMIO window that is backed by the SPI command sequencer in the SPI bus controller. This arrangement has the limitation that only byte size accesses are supported, and so we'll need to provide a separate module that take this into account.

2020-10-01regulator: qcom: labibb: Constify static structsRikard Falkeborn
The only usage of qcom_labibb_ops is to assign it to the ops field in the regulator_desc struct, which is a const pointer. The only usage of pmi8998_lab_desc and pmi8998_ibb_desc is to assign their address to the desc field in the labibb_regulator_data struct which can be made const, since it is only copied into the desc field in the labbibb_regulator_data struct. This struct is modified, but that's a copy of the static one. Make them const to allow the compiler to put them in read-only memory.

2020-10-01regulator: qcom_smd: Add PM660/PM660L regulator supportAngeloGioacchino Del Regno
The PM660 and PM660L are a very very common PMIC combo, found on boards using the SDM630, SDM636, SDM660 (and SDA variants) SoC. PM660 provides 6 SMPS and 19 LDOs (of which one is unaccesible), while PM660L provides 5 SMPS (of which S3 and S4 are combined), 10 LDOs and a Buck-or-Boost (BoB) regulator. The PM660L IC also provides other regulators that are very specialized (for example, for the display) and will be managed in the other appropriate drivers (for example, labibb).

The PM660 PMIC is very often paired with the PM660L option on SDM630/663/660 (and SDA variants) boards. The PM660 has 11 "660" LDOs (2 NMOS, 9 PMOS) and 7 HT LDOs (4 NMOS, 3 PMOS) and a quirk: the L4 regulator is unaccessible or does not exist on the PMIC. The PM660L has 8 "660" LDOs (1 NMOS, 7 PMOS) and 2 HT NMOS LDOs.

2020-10-01regulator: core: Enlarge max OF property name length to 64 charsAngeloGioacchino Del Regno
Some regulator drivers may be defining very long names: this is the case with the qcom_smd and qcom_spmi regulators, where we need to parse the regulator parents from DT. For clarity, this is an example: { "l13a", QCOM_SMD_RPM_LDOA, 13, &pm660_ht_lvpldo, "vdd_l8_l9_l10_l11_l12_l13_l14" }, pm660-regulators { ... vdd_l8_l9_l10_l11_l12_l13_l14-supply = <&vreg_s4a_2p04> ... }; Now, with a 32 characters limit, the function is trying to parse, exactly, "vdd_l8_l9_l10_l11_l12_l13_l14-s" (32 chars) instead of the right one, which is 37 chars long in this specific case. ... And this is not only the case with PM660/PM660L, but also with PMA8084, PM8916, PM8950 and others that are not implemented yet. The length of 64 chars was chosen based on the longest parsed property name that I could find, which is in PM8916, and would be 53 characters long. At that point, rounding that to 64 looked like being the best idea.

Petr reported that system freezes on r8169 driver load on a system using ether_clk. The original change was done under the assumption that the clock isn't needed for basic operations like chip register access. But obviously that was wrong. Therefore effectively revert the original change, and in addition leave the clock active when suspending and WoL is enabled. Chip may not be able to process incoming packets otherwise.

Xen is using the chip_data pointer for storing IRQ specific data. When running as a HVM domain this can result in problems for legacy IRQs, as those might use chip_data for their own purposes.

2020-10-01gpio: pca953x: Correctly initialize registers 6 and 7 for PCA957xAndy Shevchenko
When driver has been converted to the bitmap API the non-bitmap functions started behaving differently on 32-bit BE architectures since the bytes in two consequent unsigned longs are in different order in comparison to byte array. Hence if the chip had had more than 32 lines the memset() call over it would have not set up upper lines correctly. Although it's currently a theoretical case (no supported chips of this type has 32+ lines), it's better to provide a clean code to avoid people thinking this is okay and potentially producing not fully working things.

2020-10-01gpio: pca953x: Use bitmap API over implicit GCC extensionAndy Shevchenko
In IRQ handler we have to clear bitmap before use. Currently the GCC extension has been used for that. For sake of the consistency switch to bitmap API. As expected bloat-o-meter shows no difference in the object size.
