Merge tag 'tegra-for-6.2-firmware-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into soc/drivers
firmware: tegra: Changes for v6.2-rc1 This adds new BPMP ABI so that newer features can be enabled. Furthermore, the BPMP driver is updated to use iosys-map helpers to allow working with shared memory regions that are located in system memory. Apart from that, several minor cleanups are included. * tag 'tegra-for-6.2-firmware-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: firmware: tegra: Remove surplus dev_err() when using platform_get_irq_byname() firmware: tegra: Update BPMP ABI firmware: tegra: bpmp: Do not support big-endian firmware: tegra: bpmp: Use iosys-map helpers firmware: tegra: bpmp: Prefer u32 over uint32_t Link: https://lore.kernel.org/r/20221121171239.2041835-2-thierry.reding@gmail.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>
