Merge tag 'spi-fix-v6.1-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi fixes from Mark Brown: "A collection of mostly unremarkable fixes for SPI that have built up since the merge window, all driver specific. The change to the qup adding support for GPIO chip selects is fixing a regression due to the removal of legacy GPIO handling, the driver had previously been silently relying on the legacy GPIO support in a slightly broken way which worked well enough on some systems. Fixing it is simply a case of setting a couple of bits of information in the driver description" * tag 'spi-fix-v6.1-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: spi: aspeed: Fix window offset of CE1 spi: qup: support using GPIO as chip select line spi: intel: Fix the offset to get the 64K erase opcode spi: aspeed: Fix typo in mode_bits field for AST2600 platform spi: mpc52xx: Replace NO_IRQ by 0 spi: spi-mem: Fix typo (of -> or) spi: spi-gxp: fix typo in SPDX identifier line spi: tegra210-quad: Fix combined sequence
