Subject: [PATCH 02/10] pinctrl: tegra186: Fix out-of-bounds register bank index for AON drive groups
Date: Tue, 3 Nov 2026 21:29:07 +0000 [thread overview]
Message-ID: <20261103213002.1673560-3-lee@kernel.org> (raw)
In-Reply-To: <20261103213002.1673560-1-lee@kernel.org>
The Tegra186 AON pinmux controller has only a single register bank
(nbanks = 1, indexed at 0), and all PINGROUP entries in tegra186_aon_groups
accordingly specify bank 0. However, all 51 AON drive_* macro definitions
pass drv_bank = 1 as the final argument to DRV_PINGROUP_ENTRY_Y, causing
any drive configuration read or write on an AON drive group to index
pmx->regs[1] out-of-bounds.
Update the AON drive_* macro definitions to use register bank 0.
Fixes: 542baf77f092 ("pinctrl: tegra: Add Tegra186 pinmux driver")
Closes: https://sashiko.dev/#/bug/linux-a9a7165c-c5eb-463a-b7b1-24a30416b33b
