Cluster modifications delete cluster members

[cosmikwolf]

I have a vendor supplied SVD (mspm0g350x)

  <peripherals>
    <peripheral>
     <name>I2C0</name>
    < ... more attributes />
      <registers>
        <cluster>
          <dim>1</dim>
          <dimIncrement>0x18</dimIncrement>
          <dimArrayIndex/>
          <name>I2C0_GPRCM[%s]</name>
          <addressOffset>0x800</addressOffset>
          <register>
            <name>I2C0_PWREN</name>
           </register>
          ... more registers />
        </cluster>
      </registers>
    </peripheral>
  </peripherals>
                

Modifying the cluster size results in removing all the cluster elements:

I2C0:
  _modify:
    "I2C0_GPRCM\\[%s\\]":
      dim: 4

when I run with --post-validate I get this error:

fsh ❯ svdtools patch MSPM0G350X_patch.yml --post-validate
[2024-09-24T22:20:39Z ERROR svdtools::cli] by svdtools (0.3.18)
    
    Caused by:
        0: `Cluster error: Cluster must contain at least one Register or Cluster
        1: Cluster must contain at least one Register or Cluster

Attaching the svd as there were some modifications that I needed to make before I could even process it with svdtools
This is the command I needed to run to get the svd file to be processed by svdtools to begin with:
sed -e 's/read-writeonce/read-writeOnce/g' MSPM0G350X.svd
