From 9d3eb68a5385626b1f0165b386e4645dc474cb69 Mon Sep 17 00:00:00 2001 From: Mian Yousaf Kaukab Date: Wed, 28 Apr 2021 14:58:07 +0200 Subject: arm64: dts: ls208xa: remove bus-num from dspi node [ 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.
