There is no need to call the dev_err() function directly to print a
custom message when handling an error from either the platform_get_irq()
or platform_get_irq_byname() functions as both are going to display an
appropriate error message in case of a failure.
./drivers/firmware/tegra/bpmp-tegra210.c:204:2-9: line 204 is redundant
because platform_get_irq() already prints an error
./drivers/firmware/tegra/bpmp-tegra210.c:216:2-9: line 216 is redundant
because platform_get_irq() already prints an error

The shared memory used for inter-processor communication between the CPU
and the BPMP can reside either in system memory or in I/O memory. Use
the iosys-map helpers to abstract these differences away.

Use the devm_platform_ioremap_resource() helper instead of calling
platform_get_resource() and devm_ioremap_resource() separately.

firmware: tegra: Fix error return code in tegra210_bpmp_init()2021-06-01T15:06:41ZZhen Leithunder.leizhen@huawei.com2021-05-13T13:26:46Zurn:sha1:7fea67710e9f6a111a2c9440576f2396ccd92d57
When call irq_get_irq_data() to get the IRQ's irq_data failed, an
appropriate error code -ENOENT should be returned. However, we directly
return 'err', which records the IRQ number instead of the error code.

This patch adds driver for Tegra210 BPMP firmware.
The BPMP is a specific processor in Tegra210 chip, which runs firmware
for assisting in entering deep low power states (suspend to ram), and
offloading DRAM memory clock scaling on some platforms.
