Date: Mon, 26 Jul 2021 17:38:16 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Mian Yousaf Kaukab <ykaukab@...e.de>, Shawn Guo <shawnguo@...nel.org>, Sasha Levin <sashal@...nel.org> Subject: [PATCH 4.14 16/82] arm64: dts: ls208xa: remove bus-num from dspi node From: Mian Yousaf Kaukab <ykaukab@...e.de> [ Upstream commit 8240c972c1798ea013cbb407722295fc826b3584 ] On LS2088A-RDB board, if the spi-fsl-dspi driver is built as module then its probe fails with the following warning: [ 10.471363] couldn't get idr [ 10.471381] WARNING: CPU: 4 PID: 488 at drivers/spi/spi.c:2689 spi_register_controller+0x73c/0x8d0 ... [ 10.471651] fsl-dspi 2100000.spi: Problem registering DSPI ctlr [ 10.471708] fsl-dspi: probe of 2100000.spi failed with error -16 Reason for the failure is that bus-num property is set for dspi node. However, bus-num property is not set for the qspi node. If probe for spi-fsl-qspi happens first then id 0 is dynamically allocated to it. Call to spi_register_controller() from spi-fsl-dspi driver then fails. Since commit 29d2daf2c33c ("spi: spi-fsl-dspi: Make bus-num property optional") bus-num property is optional. Remove bus-num property from dspi node to fix the issue.
