The type shall be <string-list> and the value shall be of the form - "fsl,mpic-v<version>-msgr", where <version> is the version number of - the MPIC containing the message registers. - - - reg: Specifies the base physical address(s) and size(s) of the - message register block's addressable register space. The type shall be - <prop-encoded-array>. - - - interrupts: Specifies a list of interrupt-specifiers which are available - for receiving interrupts. Interrupt-specifier consists of two cells: first - cell is interrupt-number and second cell is level-sense. The type shall be - <prop-encoded-array>. - -Optional properties: - - - mpic-msgr-receive-mask: Specifies what registers in the containing block - are allowed to receive interrupts. The value is a bit mask where a set - bit at bit 'n' indicates that message register 'n' can receive interrupts. - Note that "bit 'n'" is numbered from LSB for PPC hardware. The type shall - be <u32>. If not present, then all of the message registers in the block - are available. - -Aliases: - - An alias should be created for every message register block. They are not - required, though. However, a particular implementation of this binding - may require aliases to be present. Aliases are of the form - 'mpic-msgr-block<n>', where <n> is an integer specifying the block's number. - Numbers shall start at 0. - -Example: - - aliases { - mpic-msgr-block0 = &mpic_msgr_block0; - mpic-msgr-block1 = &mpic_msgr_block1; - }; - - mpic_msgr_block0: mpic-msgr-block@41400 { - compatible = "fsl,mpic-v3.1-msgr"; - reg = <0x41400 0x200>; - // Message registers 0 and 2 in this block can receive interrupts on - // sources 0xb0 and 0xb2, respectively. - interrupts = <0xb0 2 0xb2 2>; - mpic-msgr-receive-mask = <0x5>; - }; - - mpic_msgr_block1: mpic-msgr-block@42400 { - compatible = "fsl,mpic-v3.1-msgr"; - reg = <0x42400 0x200>; - // Message registers 0 and 2 in this block can receive interrupts on - // sources 0xb4 and 0xb6, respectively. - interrupts = <0xb4 2 0xb6 2>; - mpic-msgr-receive-mask = <0x5>; - }; |
